SPECIFICATION forming part of Letters PatentNO. 289,090, dated November :27, 1883.

Application filcd March 12, 1882 3. (No model.)

pensive mechanism whereby the frame of the machine may be gradually and automatically raised or lowered by power derived from the main drivewheel, so as to suit the height of the grain and other conditions which may render it desirable to adjust the frame of the machine vertically.

To this end my invention consists in the improved construction and arrangement of parts which will be hereinafter fully described, and particularly pointed out in the claims.

. In the drawings hereto annexed, Figure 1 is a perspective View of as much of a harvestingmachiue as is necessary to illustrate my invention. Fig. 2 is a top or plan view of the same. Fig. 3 .is a side elevation, partly in section, looking toward the main drive-wheel. Fig. 4 is a rear elevation. Fig. 5 is a front elevation, partly in sect-ion. Fig. 6 is a vertical section on the line a m in Fig. Fig. 7 is a horizontal section, and Fig. 8 is a detail view.

The same letters refer to the same parts in all the figures.

A in the drawings designates the rear framebeam, and B C- two cross-girts or longitudinal beams, of the frame of a harvester to which my invention is applied. Upon the inner sides of the beams B and G are secured segments D, having slots E, the concave sides of which are toothed, as at F.

G is the main shaft or axle, upon which the main drive-wheel H is firmly secured. J ournaled loosely upon the ends of said axle are pinions I, which are fitted in the segmental slots E so as to engage the teeth F, as shown. Upon the sides of the pinions I are secured chain-wheels J, which are connected by chains K with chain-wheels L upon a shaft, M, mounted transversely in the beams B O.

N is a chain or sprocket wheel mounted loosely upon the main shaft or axle, and capable of being connected with the main drive-wheel by means of a clutch. O, operated by means of a suitable lever. (Not shown in the drawings.) A rotary motion may 111 this manner be imparted to the sprocketwheel N, whenever desired, by the operator. The shaft M is extended inwardly through the beam 13, and carries at its inner end awormwheel, P. Q U is a bracket secured to the beams A and B, and having bearings for a short longitudinal shaft, It, carrying at its forward end a worm, S, engaging the wheelP, and at its rear end a bevel-pinion, T. The bracket QU also has bearings for atransverse shaft, V, upon which two bevel gears, N A, are loosely journaled in such a manner that both of them. shall continually engage the bevel-pinion T, as shown. Upon the shaft V, between the wheels XV and X, is fitted a dou ble clutch, 13", consisting of a suitably-toothed sleeve fitted to slide upon the shaft V, with which it is connected by a spline, Y. Z is a shipping-lever pivoted upon the frame-beam A, and having a fork, A engaging the clutch B", and which may, by the said shipping-lever, be moved in either direction, so as to engage either of the gear-wheels N X, both of which are provided with clutch-teeth G" on their inner sides to engage the said clutch. The shaft V extends through the beam B, and is provided on its end with a chaiirwhecl, D", firmly secured thereon, and connected by a chain, FF, with the sprocket-wheel N on the main axle.

F and are bell-crank levers pivoted, respectively, to the upper and lower ends of the segment D upon the beam B. One of the arms of each of said levers extends beyond the slot E of said segment, and the other vertical arm of each is connected bya rod, H", with one of the arms of a T-lever, 1, pivoted upon the beam A, and having its third arm connected by a rod, J with the shipping-lever Z. The end of the shaft M has adrum, K upon which is wounda chain, L, passing over a guide-pulley, M upon the beam A, and to the other or grain side of the machine,where suitable provision is to be made for raising orlowering the said end upon the grain-wheel by power derived from the shaft M. For this purpose mechanism of anysuitable description may be employed, and it is no part of my present invention.

The operation of my invention willbe readsegment-plates D are attached.

ily understood from the foregoing description taken in connection with the drawings hereto annexed. Normally the double clutch B is located between the gear-wheelsIV and X and out of engagement with both. Normally, also, and especially when there is no necessity for some length of time of using the raising and lowering mechanism, the chain-wheelN is disconnected from the main drive-wheel. To throw the mechanism into action, the clutch O is first moved so as to connect the sprocketwheel N with the main drive-wheel H. A continuous rotary motion is thus imparted to the said sprocket wheel, and from thence through the chain E to the chain-wheel D and the shaft V and the double clutch 13*, which is connected to the said shaft by the spline Y. The shipping-lever Z may be moved either by hand or in any suitable manner, so as to throw the clutch B into engagement with either of the bevel-gears WV X, thus imparting a right or left hand revolving motion to the bevel-pinion T, and to the worm-shaftR, upon which the said pinion is mounted. Let it be supposed, for the purpose of illustration, that the clutch B engages the bevel-gear X, the shaft R will then be revolved, thus causing the shaft M, upon which the wornrwheel P is mounted, to be revolved in the direction indicated by an arrow. The chain-wheels L upon the shaft M transmit this motion, through the chains K, to the chain -wheels .I, which are secured to the pinions I, that are loose upon the main axle. The said pinions, en gaging the segment-gears F, will thus operate to lift or raise the frame to which the This applies, of course, only to the end of the frame having the main drive-wheel; but power for raising the other end of the frame as well is supplied from the shaft M by means of the chain L The lifting motion will, unless stopped by throwing the clutch 13 out of engagement with the bevel-gear X, continue until the lower ends of the slots E in the segment-plates reach the pinions I; but the pinion I, at the inner end of the axle, will then come in contact with the horizontal arm of the bell-crank lever G and operate the said lever, the connecting rod H T-lever I", connecting-rod J and the shipping-lever Z in such a manner as to throw the clutch out of engagement with the bevel-gear X, thus stopping the motion and preventing strain or injury to the machine. By throwing the clutch B into engagement with the bevelgear I, the motion may be reversed and the frame be lowered. In this case, likewise, the pinion I will, by operating the bell-crank lever F stop the motion in time to prevent injury to the machine in case the operator should neglect to do so in time, or should be otherwise employed.

Iclaim as my invention and desire to secure by Letters Patent of the United States 1. In a harvester, the combination of the axle carrying the main drive and transporting wheel, pinions journaled loosely upon the said axle, the frame provided with slotted-rackplates with which the said pinions engage, mechanism for operating the latter for. the purpose of raising or lowering the frame, and means for automatically stopping the motion of the pinions when the limits of the vertical movement of the frame are reached, as set forth.

2. The combination of the main axle G, the drive-wheel II, loose pinions I I, having chainwheels J, chain-wheel N, and clutch O, for connecting or disconnecting the latter to the drive-wheel, the frame A B G, havingsegmentplates D, provided with slots E, and teeth F, the transverse shaft M, the chain-wheels L L, and worm-wheel I mounted upon the same, the chains K, the transverse shaft V, having chain-wheel D the chain E the bevel-gears W X, mounted loosely upon the shaft V, and having clutch-teeth C, the double clutch B, splined upon the shaft V between the bevelgears NV and X, and the longitudinal shaft R, having bevel-pinion T and worm S, all arranged and operating substantially as and for the purpose set forth.

3. The combination of the frame A B C, having segment-plates D, provided with slots E and teeth F, the main shaft or axle G, having loose pinions I, engaging the teeth or racks F, means, substantially as described, for transmitting motion from the main shaft to the pinions I, the double clutch B for controlling and reversing such motion, the shipping-lever Z, T-lever 1 connecting-rod J bell-crank levers F and G, pivoted at the upper and lower ends of one of the segmentplates D, and the connecting-rods H all arranged and operating substantially as and for the purpose shown and specified.

4. The combination of the frame A B O, having segment-plates D, provided with slots E and teeth F, the main shaft or axle G, having loose pinions I, engaging the teeth or racks F, and provided with chain-wheels J, the transverse shaft M, having chain wheels L, the chains K, connecting the latter with the chainwheels J, mechanism for conveying a rotary motion in either direction from the main axle to the shaft M, mechanism for reversing such motion, the drum K upon the shaft M, and the chain L wound upon said drum, and connecting with mechanism for raising and lowering the opposite end of the frame, substantially as and for the purpose shown and specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
